Northrop Grumman successfully completes spacecraft critical design review for JWST

Northrop Grumman Corporation successfully passed the last significant mission design milestone for NASA's James Webb Space Telescope, the spacecraft Critical Design Review (CDR), five months ahead of schedule, following the replan.

16th Intl. Conference on RF Superconductivity held in Paris

Ah, Paris! The City of Lights was the setting for the SRF 2013 conference, held Sept. 22-27. The conference was the latest continuation of a series started in 1980 at Karlsruhe as a small workshop, and has grown to 412 attendees, featuring an exhibition with 20 industrial exhibitors, and offering...

Education in Cryogenics, Superconductivity: Some Updates

The following are some recent updates and additions to the information offered at CSA’s website about educational opportunities in cryogenics and superconductivity, both in classrooms and nontraditional settings, in the US and around the world.

Registration Open for ‘Foundations of Cryocoolers’ Short Course at ICC18

Registration is now open for the “Foundations of Cryocoolers” short course to be held on Monday, June 9, 2014, right before the 18th International Cryocoolers Conference (ICC18). The conference will be held June 9-12 at Syracuse University, Syracuse NY. Conference Chairman is Rich Dausman of Cryomech, Inc. and Co-Chair is...

US Gov’t Shutdown Affects Cryo, Superconductivity

In October, it would have been hard to miss the news of the 16-day US federal government shutdown, even for those located outside of the United States. The shutdown came as a result of Congress’ inability to enact legislation appropriating funds for fiscal year 2014 or to agree on a...

Use of fiberglass in the LNG market

I am doing a bit of market research on the use of fiberglass in the LNG market. What is the type and weave of fiberglass used in LNG manufacturing? Is it used aesthetically or is there an actual technical purpose for the fiberglass, such as insulation? Can you name the...

Dewar

A dewar is a type of cryostat named after Sir James Dewar, the researcher who first developed the concept of a vacuum insulated container with silvered walls to reflect thermal radiation. Dewar was the first to liquefy hydrogen, and he created the device to store his discovery. The thermos bottle...

Stirling and Gifford-McMahon Cryocoolers

Stirling and Gifford-McMahon (GM) cryocoolers are two of the most commonly used cryocoolers in cryogenics. Both devices have a significant industrial base and operate at a wide range of temperatures and capacities. The thermodynamic cycles for both of these cryocoolers are quite similar. The Stirling cycle consists of a compressor,...

Liquefied Natural Gas (LNG)

A significant commercial application of cryogenics is the liquefaction, transport and storage of natural gas. Liquefied Natural Gas (LNG) is generally 95 percent methane with a few percent ethane and much lower concentrations of propane and butane. LNG liquefies at 111.6 K. Unlike many applications of cryogenics, the motivation for...

Cryogenic Treatment of Materials

F.J. Diekman Controlled Thermal Processing, Inc. info@metal-wear.com Cryogenic Processing (also called cryogenic treatment, and incorrectly “cryogenic tempering”) is a process that uses cryogenic temperatures to modify materials to enhance their performance. Cryogenic Processing involves the slow reduction in temperature of the material to at least -300°F (-185°C) and holding the...

Cryogenics in Space

Peter Kittel University of California-Berkeley pkittel@cal.berkeley.edu Space Cryogenics is the application of cryogenics to space missions. These applications fall into two broad areas, supporting space science missions and supporting the space transportation infrastructure. Science applications: The atmosphere is opaque to much of the electro-magnetic spectrum. In space, the absence of...
